SAW-HANDLE Specification of Letters Patent. Patented March 10, 1908Application filed August 23, 1907. Serial No. 389,898.

To all whom it may concern:

Be it known that I, CHARLES M.-LARKIN, a citizen of the United States,residing at Baker City, in the county of Baker and State of Oregon, haveinvented certain new and useful Improvements in Saw-Handles, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in handles for cross-cut saws andconsists 'of the novel construction and the combination and arrangementof parts hereinafter described and claimed. 1

The object of the invention is to provide an improved handle of thiskind which will be simple, strong, durable and comparatively inexpensivein construction, which may be readily adjusted with respect to the sawblade, and by means of which the saw may be effectively held andoperated.

The above and other objects are attained in the preferred embodiment ofthe invention illustrated in the accompanying drawings in which Figure 1is a side elevation of my improved saw handle showing it applied to oneend of a cross-cut saw; Fig. 2 is a longitudinal section taken on theplane indicated by the line 2-2 in Fig. 1; and Figs. 3 and 4 areperspective views of the two adjustable and coupling members.

' In the drawings 1 denotes a portion of the saw and 2 my improvedhandle which is substantially U-shape in form so as to provide alongitudinal hand grip and two transverse or right angularly projectinghand grips 4, 5. The transversely or laterally proj ecting hand grips 4,5 are cylindrical in form and are arranged at the opposite ends of thelongitudinal hand grip 3, which latter is also of cylindrical form andhas its ends formed with concave depressions 6 to receive the hand grips4, 5. The three hand grips are secured together and united to the saw bya bolt or tierod 7 which extends through transverse apertures 8 in thehand grips 4,

5 and a longitudinalopening or bore 9 in the hand grip 3. The bolt 7 hasat its inner end a cylindrical head or enlargement 10 which is formedwith a longitudinal slot 11 to receive the saw 1 which latter isretained in said slot by a transverse rivet or similar fastening 12. Theopposite or outer end of the bolt projects beyond the outer hand grip 5and is screw threaded to receive a thumb nut 13 and washer 14 whichlatter is in the form of a substantially rectangular plate disposedlongitudinallyzupon the hand and the inner hand grip 4 are two couplingmembers 16, 17 preferably in the form of castings. The member or bladel6'has at one end a small cylindrical portion 18 and at its opposite enda large elliptical portion 19 provided with a concaved outer face 20 toreceive the hand grip 4. The other member or plate 17 has a cylindricalend 21 and an elliptical end or portion 22 formed with a longitudinalgroove 23 to receive the saw. Formed upon the opposing ends of theportions 18, 21 of the two members are serrations or corrugations 24which fit into each with respect to the other.

From the foregoing it will be seen that a handle constructed inaccordance with my invention provides an effective means for holding andoperating the saw. In sawing down a standing tree a most effective gripcan be secured by grasping the handles 3, 5, and when the saw is usedfor cuttin a horizontally disposed object the hand es 4, 5 provide themore convenient and effective gripping means. Owing to the provision ofthe coupling members 16, 17 it will be seen that the handles may beadjusted angularly with respect to the plane of the saw so that they maybe disposed at any desired angle. This adjustment is readily effected byloosening the thumb nut 13, turning the members 16, 4, 3 and 5, and thentightening the nut. It will be further noted that the handle isexceedingly simple, strong and durable in its construction and that theone bolt 7 provides an effective means for uniting the several handgrips and also securing the device to the saw.

Having I claim is:

1. A saw handle of substantially U-form comprising a longitudinal handgrip, two transverse hand grips, one being arranged at each end of thelongitudinal grip and projecting at right angles therefrom, saidlongitudinal grip being formed with a longitudinal opening or bore andthe two transverse or end grips being formed with transverse openings toaline with the one in the longitudinal grip, a clamping bolt extendingthrough the thus described my invention, what grip 5 and having aconcaved inner face '15 to receive said hand grip. Arranged'upon theinner end of the bolt between the saw" other and prevent rotary movementof one alined openings in said grips whereby the latter are rotatablymounted upon the bolt, and a coupling device arranged upon the bolt andconsisting of two separable, non-rotatably engaged members, one beingadapted to receive the saw and the other to receive the handle,substantially as and for the purpose set forth.

2. A saw handle comprising a hand grip portion formed with an opening, ascrew bolt arranged in the opening in the hand grip portion whereby thelatter may turn u on the bolt, one end of the bolt being forrne with ahead for the attachment of the saw and its ling device arranged upon thebolt and consisting of two separable non-rotatably engaged members, onebeing formed with a groove or notch to receive the saw and the otherbeing shaped to engage said hand grip CHARLES M.
